Table S2. All Settings and Default Values Needed by User to Configure Scisola

Variable Description Default Value
center longitude The longitude value of the central location for the given distance range, within which events are going to be triggered -
center latitude The latitude value of the central location for the given distance range, within which events are going to be triggered -
distance range (km) The distance range value (in kilometers) from central location, within which events are going to be triggered 1000
min magnitude Events with magnitude greater or equal to the minimum magnitude value are going to be triggered 3.5
distance selection The distance selection that will be applied according to the rules set by the user. For example, having the suggested set of values for a magnitude 4.7 earthquake, scisola will choose stations that are within 80 and 200 km from the epicenter’s location. Scisola doesn’t take the sequence of rules into account. To set rules, the user needs to calibrate the rules by testing datasets of events offline to find suitable configurations. If the network generates more than one-digit magnitudes, scisola will round them up to one decimal. 3.5 <= magnitude <= 4.0 and 10 <= distance <= 100
4.1 <= magnitude <= 4.5 and 50 <= distance <= 150
4.6 <= magnitude <= 5.0 and 80 <= distance <= 200
5.1 <= magnitude <= 5.5 and 90 <= distance <= 250
5.6 <= magnitude <= 6.0 and 110 <= distance <= 500
6.1 <= magnitude <= 12.0 and 330 <= distance <= 1000
number of sectors The number of the azimuthal sectors that must contain stations in order to execute the inversion procedure 4
stations per sector The maximum number of stations that will be chosen in the azimuthal distribution phase: if the number of stations are more than this value, scisola will remove those stations that have low priority and are farther from the epicenter’s location 3
edit database button This button triggers the stations window where the user can see the streams that are imported to scisola and edit their information -
number of sources The number of trial sources distributed above and below the automatic depth estimation 20
step search (km) The step between two adjacent trial sources in depth 2
clipping threshold The clipping threshold value according to which scisola will decide if a stream is clipped or not (i.e., a clipping threshold for waveforms): For example, 0.80 means that, if the recorded amplitude exceeds 80% of the theoretical maximum amplitude of the digitizer, the trace is considered as clipped 0.80
crustal model path The path to the crustal model -
start The start point of time grid search, given in dt (i.e., sampling interval of data defined by the choice of inversion time): dt is defined as tl/8192, in which tl is the time window length. (See Sokos and Zahradnik, 2008, for details.) −75
end The end point of time grid search 75
step search The step point of time grid search 2
inversion time The amount of data (in seconds) that will be inverted. For example, having the suggested set of values for a magnitude 4.7 earthquake, scisola will choose a tl of 327.68 s. Scisola doesn’t take the sequence of rules into account. To set rules, the user needs to calibrate the rules by testing datasets of events offline to find suitable configurations. If the network generates more than one-digit magnitudes, scisola will round them up to one decimal. 3.5 <= magnitude <= 5.5 and tl = 327.68
5.6 <= magnitude <= 12.0 and tl = 409.6
inversion frequency The inversion frequency band that will be used for inversion. For example, having the suggested set of values for a magnitude 4.7 earthquake scisola will choose a frequency band for the inversion procedure (e.g., 0.04, 0.05, 0.08, 0.09 Hz). Scisola doesn’t take the sequence of rules into account. To set rules, the user needs to calibrate the rules by testing datasets of events offline to find suitable configurations. If the network generates more than one-digit magnitudes, scisola will round them up to one decimal. 3.5 <= magnitude <= 4.2 and frequencies = [0.06, 0.07, 0.09, 0.1]
4.3 <= magnitude <= 5.5 and frequencies = [0.04, 0.05, 0.08, 0.09]
5.6 <= magnitude <= 6.0 and frequencies = [0.02, 0.03, 0.06, 0.07]
6.1 <= magnitude <= 12.0 and frequencies = [0.001, 0.005, 0.01, 0.02]
check interval (sec) The interval time (in seconds) that the watcher will check for new incoming event 300
process triggering delay (sec) The delay time (in seconds) before triggering an incoming event; this can be used to give seedlink time to gather data in its ringbuffers 0
process timeout (sec) The time (in seconds) that, if completed, will terminate the procedure 3600
results folder The path to the scisola’s result folder: Inside this folder, scisola will create subfolders by using the origin’s date and time as a folder name. While inside these subfolders, it will create subfolders by using the date and time that triggered the process. Inside these folders the results of the calculation will be saved. -
update database button / reset button By clicking this button, scisola will retrieve the station/stream information from SeisComP3’s database; if reset is enabled, it will delete older-streams and station information from the scisola database. -
seisComP3 path The path to the SeisComP3 folder -
scevtls path The path to the scevtls module of SeisComP3 folder scevtls
scxmldump path The path to the scxmldump module of SeisComP3 folder scxmldump
slinktool path The path to the slinktool module of SeisComP3 folder slinktool
slinktool host The host value of the slinktool module of SeisComP3 localhost
slinktool port The port value of the slinktool module of SeisComP3 18000
ISOLA path The path to the ISOLA folder -
